CPT® Code 50542

Laparoscopy, surgical; ablation of renal mass lesion(s), including intraoperative ultrasound guidance and monitoring, when performed

The procedure described by CPT® Code 50542 involves a laparoscopic surgical technique aimed at ablating renal mass lesions. Ablation refers to the destruction of tissue, in this case, cysts or mass lesions located in the kidney. The physician utilizes various methods to achieve this destruction, which may include cryoablation, radiofrequency ablation (RFA), high-intensity focused ultrasound (HIFU), or laser thermal ablation. The laparoscopic approach allows for minimally invasive access to the kidney, which is achieved by creating a pneumoperitoneum and inserting trocars. The laparoscope is introduced through the umbilical port, providing visualization of the kidney and its lesions. Once the lesions are identified, specific ablation instruments are employed to treat them. The procedure is carefully monitored, particularly in the case of cryoablation, where ultrasound guidance is used to ensure that the freezing effect adequately encompasses the lesion. This meticulous approach helps to minimize damage to surrounding healthy tissue while effectively treating the targeted lesions. Following the ablation, the surgical instruments are removed, and any necessary drains are placed before closing the incisions. This procedure is specifically coded as 50542 for the ablation of renal mass lesions, distinguishing it from other codes that may pertain to different types of renal ablation procedures.
